<p>Methods and devices providing transmyocardial blood flow or coronary revascularization for the treatment of coronary atherosclerosis and resulting myocardial ischemia by increasing the flow of blood from one or more oxygenated blood sources within the patient to one or more sites selected in the arterial vascular system of the heart using a channel (42) for maintaining and regulating blood flow therebetween. A valved conduit (48) or a self-maintained channel (42) is created between the left ventricle (20) reservoir of oxygenated blood and the coronary artery (26) distal to an area of obstruction by surgical and percutaneous methods. Preferably, the conduit (48) or self-maintaining channel (42) integrally regulates the flow of blood between the oxygenated blood source and the site selected in the arterial vascular system of the heart wherein an increase in blood flow is desired.</p> |
